NativeScript Brightness

A plugin for manipulating your device's screeen brightness in NativeScript Android and iOS apps.

Installation

Run the following command from the root of your project:

tns plugin add nativescript-brightness

This command automatically installs the necessary files, as well as stores nativescript-brightness as a dependency in your project's package.json file.

This plugin requires <uses-permission android:name="android.permission.WRITE_SETTINGS"/> to be added in the android manifest.

Usage

To use the brightness module you must first require() and instantiate it:

// JavaScript
var nativescriptBrightness = require("nativescript-brightness");
var brightness = new nativescriptBrightness.Brightness();

Or if you’re using TypeScript, import the module:

// TypeScript
import { Brightness } from 'nativescript-brightness';
const brightness = new Brightness();

After you have a reference to the module you can then call its get() and set() methods. For example, the code below updates you screen's brightness with an intensity setting of 25%.

The intensity can be set to a value from 1 to 100.

// TypeScript
import { Brightness } from 'nativescript-brightness';
const brightness = new Brightness();

brightness.set({
    intensity: 25
});
